Abstract: An implantable medical lead includes a first defibrillation electrode and a second defibrillation electrode. The implantable medical lead further includes a pacing electrode configured to deliver a pacing pulse that generates an electric field proximate to the pacing electrode. The implantable medical lead further includes a shield disposed over a portion of an outer surface of the pacing electrode and extending laterally away from the pacing electrode. The shield is configured to impede the electric field in a direction from the pacing electrode away from a heart. The implantable medical lead further includes a conductive surface disposed on the shield and electrically coupled to the pacing electrode.

Abstract: In some examples, a medical device includes an elongated structure configured to extend from an access point of a patient through an intercostal space within the patient. The medical device may further include a plurality of electrodes comprising a first subset of electrodes and a second subset of electrodes, where at least the first subset of electrodes is carried on a distal portion of the elongated structure. The first subset of electrodes of the plurality of electrodes may be configured to deliver electrical therapy to a heart of the patient or sense cardiac activity. The second subset of electrodes of the plurality of electrodes may be configured to deliver energy to tissue proximate a ribcage of the patient to reduce a sensation in one or more intercostal nerves.

Abstract: Systems, devices, and methods for performing respiratory-based cardiac remodeling pacing therapy are described in this disclosure. A patent's respiration may be monitored, and the lower pacing limit for the cardiac remodeling pacing and support pacing therapy delivered to a patient may be adjusted based on the monitored respiration to achieve or restore respiratory sinus arrhythmia.

Abstract: Implantable medical systems enter an exposure mode of operation, either manually via a down linked programming instruction or by automatic detection by the implantable system of exposure to a magnetic disturbance. A controller then determines the appropriate exposure mode by considering various pieces of information including the device type including whether the device has defibrillation capability, pre-exposure mode of therapy including which chambers have been paced, and pre-exposure cardiac activity that is either intrinsic or paced rates. Additional considerations may include determining whether a sensed rate during the exposure mode is physiologic or artificially produced by the magnetic disturbance. When the sensed rate is physiologic, then the controller uses the sensed rate to trigger pacing and otherwise uses asynchronous pacing at a fixed rate.

Abstract: This disclosure describes systems, devices and techniques for improving the longevity of battery life in a device. An example first device includes communication circuitry configured to communicate with a second device and processing circuitry configured to determine an expected amount of data to be transmitted by the second device to the first device. The processing circuitry is configured to determine that the expected amount of data to be transmitted by the second device to the first device is greater than or equal to a predetermined data threshold and based on the expected amount of data to be transmitted being greater than or equal to the predetermined data threshold, determine that a predetermined restriction is met. The processing circuitry is configured to, based on the predetermined restriction being met, control the communication circuitry to transmit an instruction to the second device.

Abstract: In some examples, this disclosure describes a method for identifying a position within a patient for a first implantable medical device (IMD) to be implanted to facilitate tissue conductive communication (TCC) between the first IMD and a second IMD implanted within the patient. In some examples, the method includes storing model data that associates patient parameter data and second IMD position data with first IMD positions based on TCC communication performance, receiving patient parameter data indicating one or more anatomical or physiological parameters of the patient, receiving second IMD position data, performing analysis by at least one of comparing the model data to the patient parameter data and the second IMD position data, performing real-time computer simulations, or a combination of comparing and performing simulations, and outputting to a user an indication of the position for the first IMD to be implanted within the patient based on the analysis.

Abstract: Techniques are disclosed for using a rate of wireless telemetry of an implantable medical device (IMD) to estimate a remaining longevity of a power source of the IMD. For example, the IMD sets a timer indicative of a remaining power capacity of the power source until a recommended replacement time (RRT) threshold. The IMD determines a power consumption of the IMD due to telemetry and updates, based on the power consumption of the IMD due to telemetry, the timer indicative of the remaining power capacity of the power source. The IMD determines, based on expiration of the timer indicative of the remaining power capacity of the power source, that the power source has reached the RRT threshold. In some examples, the IMD may output, to an external device and for display to a user, an indication that the power source has reached the RRT threshold.
